Lub valve ntawm tshuaj twj tso kua mis yog ib qho cuab yeej siv los tswj cov dej ntws, siab thiab ntws kev taw qhia. Daim ntawv no qhia txog cov qauv thiab hom li qub siv hauv ntau yam khoom siv, suav nrog cov khoom siv hauv cov khoom siv polypropylene. Polypropylene yog lub siab molecular compound polymerized nrog propylene li raw khoom. Cov cuab yeej tsuas yog xav tau lub rooj vag valve, nres valve, kos valve, koob valve, pob valve thiab ntws valve.
Hom li qub rau cov twj siv tshuaj
Valves rau cov nroj tsuag ethylene: ethylene cog yog cov khoom siv ntawm kev lag luam petrochemical, uas xav tau ntau yam li qub. Lub rooj vag valve, lub ntiaj teb valve, kos valve thiab lifting pas nrig pob valve account rau feem ntau, ntawm cov rooj vag valve yuav tsum tau ua tus coj. Loj ethylene thiab high-pressure polyethylene nroj tsuag kuj xav tau ultra-siab kub, qis kub thiab ultra-siab siab valve series khoom.
Valves rau chav sib cais huab cua: "air separation" txhais tau tias huab cua sib cais. Lub tsev feem ntau xav tau nres valve, kev nyab xeeb valve, kos valve, tswj lub valve, pob valve, npauj npaim valve thiab qis-kub valve.
Li qub rau cov roj refining units: feem ntau ntawm cov li qub uas yuav tsum tau ua rau cov roj refining units yog cov kav dej, feem ntau yog lub rooj vag li qub, lub ntiaj teb li qub, kos li qub, kev nyab xeeb li qub, pob li qub, npauj npaim li qub thiab cov cuab yeej. Ntawm lawv, qhov kev thov rau lub rooj vag li qub suav txog li 80 feem pua ntawm tag nrho cov li qub thiab li qub suav txog 3 feem pua ~ 5 feem pua ntawm tag nrho cov peev txheej ntawm chav tsev.
Li qub rau cov nroj tsuag hluavtaws ammonia: vim yog cov khoom siv hluavtaws ammonia sib txawv thiab cov txheej txheem purification, lawv cov txheej txheem ntws sib txawv, thiab kev ua haujlwm ntawm cov khoom siv li qub kuj txawv. Tam sim no, cov khoom siv hluav taws xob hauv tsev feem ntau xav tau lub rooj vag valve, nres valve, kos valve, ntws valve, npauj npaim valve, pob valve, diaphragm valve, regulating valve, koob valve, kev ruaj ntseg valve thiab kub thiab kub tsis tshua muaj valve. Ntawm lawv, qhov nres valve tso nyiaj rau 53.4 feem pua ntawm tag nrho cov ntaub ntawv ntawm li qub siv nyob rau hauv lub cuab yeej, lub rooj vag valve account rau 25.1 feem pua, lub valve tso nyiaj rau 7.7 feem pua, kev ruaj ntseg valve account rau 2.4 feem pua, thiab regulating valve, tsis tshua muaj kub valve thiab lwm tus account rau 11.4 feem pua
Li qub rau cov khoom siv tshuaj fiber ntau: cov khoom siv tshuaj fiber ntau muaj xws li polyester, acrylic thiab vinylon. Cov khoom uas yuav tsum tau muaj xws li pob valve, tsho valve, tsho pob valve, tsho lub rooj vag valve thiab jacketed nres valve.
Valves rau acrylonitrile chav tsev: chav tsev feem ntau xav tau li qub uas ua raws li API cov qauv, feem ntau suav nrog lub rooj vag valve, nres valve, kos valve, pob valve, ntws valve, koob valve thiab ntsaws valve. Ntawm lawv, rooj vag valve suav txog li 75 feem pua ntawm tag nrho cov li qub.
